When normal Woven fabric, warp thread need simultaneously pump to be formed weaving be open can closure situation, cause through
The variation of yarn tension moment.
(1) when Warp opening maximum tension maximum: tension suffered by walking beam it is maximum and to suffered tension to downside right angle under
Direction is swung, and when Warp opening is fully finished, and walking beam is maximum to the lower direction oscillating quantity of loom 1.Walking beam is to suffered
The warp tension being subject to is converted to driving torque, the tension that walking beam is subject to while the downward right angle orientation of tension is swung
Fixed beam is reached, walking beam is mounted on the fixed back rest by support base, and fixed beam is passed the driving torque being subject to by connecting rod
It is handed to tension spring, tension spring variation length is maximum at this time.With institute's Impact direction and size length variation occurs for tension spring,
And tension is transferred to tension sensor.
(2) when Warp opening is closed: it is most lower and minimum to suffered tension to downside right angle orientation to swing beam stress.Walking beam
The warp tension being subject to is converted to driving torque while swinging to direction under loom, the tension that walking beam is subject to passes
To fixed beam, walking beam is mounted on the fixed back rest by the second support base, and fixed beam passes through the driving torque that connecting rod will be subject to
It is transferred to tension spring, tension spring length variation at this time is minimum.Tension spring occurs length with institute's Impact direction and size and becomes
Change, and tension is transferred to tension sensor.
When warp tension changes, pass through walking beam 16, the second support base 34, the fixed back rest 17, connecting rod 11, tension spring 10
Tension is reached into tension sensor 9.The Tensity size signal received is fed back to loom control system, loom by tension sensor
Control system passes through the tension set and calculates the revolving speed and torque of compensation program control servo motor 20, then passes through power transmission
Process: reduction gearbox 21, deceleration worm gear case 22, the 4th transmission gear 29, transmission idle pulley 23, third transmission gear 24, second are driven
Gear 12 and the first transmission gear 13 are to warp thread winding up roller 18.Revolving speed and torque that servo motor 20 exports are transferred to warp thread winding up roller
18, the revolving speed of warp thread winding up roller 18 is controlled, the revolving speed by controlling warp thread winding up roller 18 controls tension variation, makes the tension-proof of warp thread
In the tension range of setting, to realize the stability loom weaving process of warp tension.
The course of work: servo motor 20 rotates and drives reduction gear box 21, deceleration worm gear case 22, the 4th transmission gear
29, idle pulley 23, third transmission gear 24, the first transmission gear 12, the second transmission gear 13 and warp let-off winding up roller 18 is driven to turn simultaneously
Dynamic, warp thread 6 is pulled by warp let-off winding up roller 18, while warp thread pressure roller 19 compresses 6 warp thread, and the winding of warp let-off winding up roller 18 simultaneously actively sends out warp
Yarn 6, walking beam 16 are swung up and down by 6 tension variation of warp thread, drive fixed beam 17 to rotate while walking beam 16 is swung, and 17 is fixed
The driving torque being subject to is transferred to tension spring 10,10 front and back Compression and Expansion of tension spring by the swing of 11 connecting rods by beam
Force snesor 9, tension sensor receive tension signal and are simultaneously sent to electric-control system, and control system is by the signal of tension sensor 9
20 servo motor revolving speeds are controlled by calculating.
The device controls walking beam when loom is weaved by tension spring and tension sensor, with the variation of warp tension
The amplitude of fluctuation of oscillating back rest is controlled, and tension variation is driven to the control system of loom, keeps the steady of weaving warp yarns tension
It is fixed.
The active let-off motion of the utility model is low suitable for weaving densities such as flat filaments, the fast fabric of weaving speed.It replaces
For warp thread warp beam, avoids because weaving speed leads to the case where often replacing warp beam fastly, knitting for special low-density kind is turned up
Make efficiency and cost.Automatically the active let-off motion adjusted the speed is eliminated using warp beam, and the warp thread of bank is directly passed through warp thread
Winding up roller is directly pulled in and is sent out, and is eliminated by warp thread in warp beam, then replaces the repeated work of warp beam, improves weaving effect
Rate reduces weaving cost.
The above, some principles of the utility model that only explains through diagrams, this specification are not intended to this is practical
It is novel to be confined in the shown specific structure and the scope of application, thus it is all it is all may be utilized accordingly modify and wait
Jljl belongs to the applied the scope of the patents of the utility model.
